Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Acute oral toxicity (LD50 value) of 1,3-dihydro-1-oxoisobenzofuran-5-carbonitrile was examined for 6 hours in male/female Rattus norvegicus species at the dose concentration of 2172.98 mg/kg. This value suggest that the chemical 1,3-dihydro-1-oxoisobenzofuran-5-carbonitrile is non toxic to organism Rattus norvegicus by oral route.
